Loading and showing interstitial AD

Interstitial Ad – AdListener
loadAd -> onAdLoaded -> show, isLoaded

public class InterstitialActivity extends Activity {
	private Button mShowButton;
	private InterstitialAd mInterstitial;

	@Override
	public void onCreate(Bundle savedInstanceState){
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_interstitial);

		mShowButton = (Button) findViewById(R.id.showButton);
		mShowButton.setEnabled(false);
	}

	public void loadInterstitial(View unusedView){
		mShowButton.setEnabled(false);
		mShowButton.setText("Loading Interstitial");

		mInterstitial = new InterstitialAd(this);
		mInterstitial.setAdUnitId("ca-app-pub-xxxx/xxxx");
		mInterstitial.astAdListener(new ToastAdListener(this){
			@Override
			public void onAdLoaded(){
				super.onAdLoaded();
				mShowButton.setText("Show Interstitial");
				mShowButton.setEnabled(true);
			}
			@Override
			public void onAdFailedToLoad(int errorCode){
				super.onAdFailedToLoad(errorCode);
				mShowButton.setText(getErrorReason());
			}
			});
			AdRequest.on = new AdRequest.Builder().build();
			mInterstitial.loadAd(ar);
		}

	public void showInterstitial(view unusedView){
		if (mInterstitial.isLoaded()){
			mInterstitial.show();
		}
		mShowButton.setText("Interstitial Not Ready");
		mShowButton.setEnabled(false);
	}
}

loadInterstitial
-Create InterstitialAd
-Set AdUnit Id
-Create Listener – onAdLoaded – show, onAdFailedToLoad – error
-Create AdRequest & LiadAd

Implementing an interstitial AD

InterstitialActivity
callback: loadInterstitial
Disable button
Set text to “Loading Interstitial”
Property: mShowButton
callback: showInterstitial (empty)
set to disable in onCreate

interstitial_ad_unit_id

<LinearLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:id="@+id/linearLayout"

</LinearLayout>	

public class InterstitialActivity extends Activity {
	private Button mShowButton;

	@Override
	public void onCreate(Bundle savedInstanceState){
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_interstitial);

		mShowButton = (Button) findViewById(R.id.showButton);
		mShowButton.setEnabled(false);
	}

	public void loadInterstitial(View unusedView){
		mShowButton.setEnabled(false);
		mShowButton.setText("Loading Interstitial");
	}

	public void showInterstitial(view unusedView){
	}
}

Adding AdListener

import ...

public class ToastAdListener extends AdListener {
	private Context mContext;
	private String mErrorReason;

	public ToastAdListener(Context context) { this.mContext = context; }

	@Override
	public void onAdLoaded(){
		Toast.makeText(mContext,
			"onAdLoaded()",
			Toast.LENGTH_SHORT).show();
	}

	@Override
	public void onAdOpened(){
		Toast.makeText(mContext,
			"onAdOpened()",
			Toast.LENGTH_SHORT).show();
	}
}

Banner Ad

package com.example.adviewer;

import ...

public class BannerActivity extends Activity {
	private AdView mAdView;

	@Override
	protected void onCreate(Bundle savedInstanceState){
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_banner);

		mAdView = (AdView) findViewById(R.id.adView);
		AdRequest adRequest = new AdRequest.Builder()
			.build();
		mAdView.loadAd(adRequest);
	}
}

AdListener
public void onAdLoaded()
public void onAdFailedToLoad(int code) {AdRequest Error}
public void onAdOpened()
public void onAdLeftApplication() (e.g. BROWSER)

Mapper and Reducer

import sys
import string
import logging

from util import mapper_logfile
logging.basicConfig(filename=mapper_logfile, format='%(message)s',
	level=logging.INFO, filemode='w')

def mapper():
	for line in sys.stdin:

		data = line.strip().split(",")
		if len(data) != 12 or data[0] == 'Register':
			continue
		print "{0}\t{1}".format(data[3], data[8])

mapper()

import sys
import logging

from util import reducer_logfile
logging.basicConfig(filename=reducer_logfile, format='%(message)s',
	level=logging.INFO, filemode='w')

def reducer():

	aadhaar_generated = 0
	old_key = None

	for line in sys.stdin:
		data = line.strip().split("\t")

		if len(data) != 2:
			continue

		this_key, count = data
		if old_key and old_key != this_key:
			print "{0}\t{1}".format(old_key, aadhaar_generated)

			aadhaar_generated = 0

		old_key = this_key
		aadhaar_generated += float(count)

	if old_key != None:
		print "{0}\t{1}".format(old_key, aadhaar_generated)

reducer()

Mapper

def mapper():

	for line in sys.stdin:

		data = line.strip.split("")

		for i in data:
			cleaned_data = i.translate(string.maketrans("",""), string.punctuation).lower()
			print "{0}\t{t}".format(cleaned_data,1)

			mapper()

Reduce stage -> reducer

import sys

def reducer():
	word_count = 0
	old_key = None

	for line in sys.stdin:
		data = line.strip().split("\t")

		if len(data) != 2:
			continue

		if old_key and old_key != this_key: 
			print"{0}\t{1}".format(old_key, word_count)
			word_count = 0

		old_key = this_key
		word_count += float(count)

	if old_key != None:
		print "{0}\t{1}".format(old_key, word_count)

Scatter Plot

Line Chart
– Mitigate some shortcomings of scatterplot
– Emphasize trends
– Focus on year to year variability, not overall trends

LOESS Curve
– Emphasize long term trends
– LOESS weighted regression
– Easier to take a quick look at chart and understand big picture

Multivariate
– How to incorporate more variables
– Use an additional encoding
– Size
– Color / Saturation

Basics of mapreduce
Mapreduce is parallel programming model

python dictionary
{“alice”:1, “was”:1, “of”:2,…”do”:1}

Data Types

– Numeric data
A measurement (e.g. height, weight) or count(e.g. HR or hit)
Discrete and continuous
discrete: whole numbers(e.g., 10, 34, 25)
continuous: only number within range(e.g., 250, /357., .511)

Categorical Data
Represent characteristics(e.g., position, team, hometown, handedness)
can take on numerical values, but they don’t it have mathematical meaning
ordinal data
categories with ome orders or ranking
vary low average high

Time- series data
– data collected via repeated measurements over time
– example: average HR

from pandas import *
from ggplot import *

def lineplot_compare(hr_by_team_year_sf_la_csv):
	hr_year = pandas.read_csv('hr_by_team_year_sf_la.csv')
	print ggplot(hr_year, aes('yearID', 'HR', color='teamID')) + geom_point() + geom_line() + ggtitle('Total HRs by Year') + xlab('Year') + ylab('HR')

if __name__ == '__main__':
	lineplot_compare()
